考察结果:北纬36°线上海拔3,300m的高原,其uv线的辐射强度是同纬度平原处的2.01倍,故高原居民是强烈uv线伤害的主要对象。为飞预防uv线对机体伤害,笔者研究了uv线对某些物质的透射率:各种布料的透射率是4.2～12％,太阳镜是2.4％,纱窗布和玻璃分别为20～59％,因此,高原居民夏季戴凉帽、不穿短衣、裤,戴太阳镜子,完全可以保护双眼和裸露的皮肤。在具有纱窗的居室或封闭的阳台内进行日光浴也是十分安全的。 The survey results show that the radiation intensity of the uv line at the elevation of 3,300m above the 36 ° north latitude line is 2.01 times that of the plain at the same latitude, so the plateau residents are the main targets of the intense uv line injury. To prevent uv line flying on the body damage, I studied the uv line transmittance of some substances: a variety of fabric transmittance 4.2 ~ 12%, sunglasses 2.4%, gauze cloth and glass were 20 to 59%, respectively, Therefore, plateau residents wearing summer hat, do not wear shorts, pants, wearing sun glasses, can protect both eyes and bare skin. It is also very safe to sunbathe in a veranda or enclosed balcony.
